To all whom it may concern: I

Be it known that I, LOUIS H. ORR, citizen of the United States, and resident of the city of New 'York, in the county of New York and State of New York, have invented certain new and useful Processes for Partially Simulating Hand-Made Paper, of which the following is a specification.

My invention relates to a process for producing textile effects on paper surfaces, and has for an object to approximate an imitation of certain types of hand made paper.

In the class of paper products referred to, among which Japanese hand made distinctive, material formed in such manner face thereof appear what I aper, there is seen a eature, because it is that upon the surshall designate as spots or patches of the fibers that existed in the materials from which the paper is made. In these papers the resulting designs of such fibrous portions are of irregular shape and arrangement, appearing in more or less general uniformity upon the surface to produce a peculiar flecked or dappled efl'ect, present in the aforesaid style of paper. While the strands of fiber appear in varying forms and figures, as pointed out, in each individual patch there is a tendency toward approximate parallel arrangement of the fiber. Likewise, the strands in one patch may run at right angles to the prevailing direction of those of an adjacent group, or in a direction slightly varying relatively thereto, or it may be the strands are in the same general arrangement. Furthermore, there may be an entire absence of fibrous appearance between the fiber marked portions, and the strands of one group may seem to disappear under the threads of an adjacent area, the direction of the individual fibers, however, varying ap parently according to no fixed rule.

My process therefore may in general terms be described as consisting in reproducing a printed sheet simulating the peculiar surface effect of the hand made paper of the type described, having reference especially to the said Japanese variety thereof.

Having reference to the drawings:

Figure l in diagrammatic form represents the successive steps followed in attaining the result of my process.

Fig. 2 represents the face of a sheet of paper produced in the preliminary steps of the process.

for example is the so-called,

The numeral 1 represents a surface showing the effect produced in the first stages of my process.- 2 is arepresentation of individual fiber strands as they appear at the surface of a hand made paper, forming areas of fibrousappearance, which I have termed the fiber patches 3, meral 4 marks similar areasintermediate the fibrous patches 3. where brushesof whitish coloring are laid on so as to slightly overlap surrounding portions of fibrous sections. In carrying out my invention, there'fore,'as a first step to this end, I trace upon a sheet of light colorin dark lines, such as those marked with commercial india ink, groups of fine lines 2 designed to resemble more or less closely the fiber strands which constitute the aforementioned fibrous areas, such for example as characterize the said J apanese hand made paper above mentioned. These markings are made to follow similar diversity of direction and arrangement generally as appears in the paper of which an imitation is sought to be made by my process. This may be conveniently and most satisfactorily accomplished by select ing a sample of the paper thus to be si1nu In like manner the nu-v lated and tracing ink lines along typical fiber threads that distinguish the so-called patches above attended to.

I then spread upon the sheet prepared in the manner above described in irregular brushes of Chinese white or other light tinted colors the flecked areas 4 with the same gen eral arrangement and irregularity as the original patches 3, but adapted primarily to cover the intervening spaces between the aforesaid patches of fibrous reproductions. The dashes of wash color are preferably made of Chinese white and slightly overlap the edges of the fibrous drawn patches so as to blend the ends of the'lines or markings representing the fiber strands in such manner as to suggest the disappearance of the end of the natural fiber into the surface in the diversified manner above referred to.

I then reproduce by the photographic process, in the form of the well known half tone plate, the result of the preceding steps in which the black lines representing fiber lines are rendered somewhat less distinctive in having been thus reproduced in the form of a half tone plate, and then as a final step I imprint with printers ink upon a suitably selected paper surface the half tone thus *lQ reduce apleasing eff prochleecl, ever whielf. may be spread 1 any desired tint or color by means of a printer sh e e z f he tint block, Which permits half tone thus prepared andprocluced t0 tained by the several Midi? f permeatetypedeserieea but a f-esthti value or its owm late meteorbye pnoteg-rapmc e' CODSlStS HIQ first, placing upon a'sheet of V aper by said hmo plat said iin re sien b1ae1- ,co'lbr asdesired,
